Title: Food and drink cooler for automobiles
Inventor: BESSEY ALAN L
IPC: B60N3/10
Filed: 1988-03-18
Granted: 1991-03-12
Abstract: FOOD AND DRINK COOLER FOR AUTOMOBILES     ABSTRACT OF THE DISCLOSURE    A food and drink cooler is provided for automobiles having a "ski hole" in a partition between the trunk and the passenger compartment.  The cooler is mounted in the vehicle trunk and has a top closure lid and a closeable portal in an upstanding wall.  The portal includes a hub extending from the wall and positionable through the "ski hole" so that a passenger in the vehicle may have access to the interior of the cooler.  A closure member closes the portal when not in use.  The cooler includes a false floor which has drain holes for permitting melted ice to drain down onto the base of the cooler, and the water so melted may flow through a drain plug at the bottom of the cooler to tubing connecting the plug to the exterior of the vehicle.  The cooler also includes a water and ice dam which precludes water and ice from flowing out through the portal when the closure member is removed and the vehicle is in motion.

Title: Gas laser apparatus, method and turbine compressor therefor
Inventor: NILSEN CARL J
IPC: H01S3/223
Filed: 1988-03-18
Granted: 1993-08-10
Abstract: Abstract of the Disclosure A fast axial flow gas laser apparatus comprising an at least essentially closed loop defining a flow path for a laser gas, an arrangement for exciting gas flowing in the loop of the apparatus to cause the gas to lase, and a regenerative compressor for flowing gas through the closed loop along the flow path.  The compressor is capable of operating with a pressure ratio sufficient to flow the gas along at least a portion of the loop at a speed at least half the speed of sound in the gas with inlet pressures of only a small fraction of an atmosphere.  The uniform dis-charge pressure of the compressor results in a uniform laser discharge or output.  A positive pressure fluid pressure seal prevents lubricant at a bearing support for the impeller shaft of the compressor from moving to the impeller and possibly contaminating the laser gas being compressed thereby and also prevents surrounding air from contaminating the laser gas.  The pressurized fluid of the seal is permitted to migrate into the laser gas as make-up gas.  The compressor is capable of moving gas through the laser at speeds approaching the speed of sound for high power output from the laser without power fluctuations and with minimal service requirements and long life while occupying only a small area within an existing laser cabinent.

Abstract: PRESS SECTION WITH SEPARATE PRESS NIPS IN A PAPER MACHINE     ABSTRACT OF THE DISCLOSURE            A press section of a paper machine comprises, in the direction of web run, at least three separate press nips for removing water from a web, the web passing between two fabrics in each of the three nips.  Dewatering of the web takes place through both faces of the web at least in the first press nip which is formed between two open-faced press rolls.  The second and third press nips are formed between an open-faced roll and one of an open-faced roll and a smooth-faced roll.  According to the inven-tion, the press section includes two upper fabrics and two lower fabrics, the first upper and lower fabrics in the direction of web run being water-receiving press fabrics, one of which constitutes a press fabric only in the first press nip, the other fabric con-stituting a press fabric both in the first and second press nips.          One of the second upper and lower fabrics is a water-receiving press fabric, the other being a water-non-receiving transfer fabric adapted to receive minimal amounts of water, if any.  The web is transferred on the transfer fabric after the third press nip as a closed draw into the drying section which follows the press section.

Title: Simple coefficient half-bandwidth digital filter for video data compression
Inventor: MICHENER JAMES A
IPC: H04B14/04
Filed: 1988-05-31
Granted: 1992-10-06
Abstract: Abstract of the Disclosure A digital data rate compression system accepts an input digital signal having A plurality of samples at a given rate and outputs a digital signal at one-half of the given rate, or as an expansion system outputs a digital signal at twice the given rate.  The digital data rate reduction technique uses multi-rate digital filtering in the form of a half bandwidth filter.  In the case of the digital filter the input digital signal is separated into even and odd samples which are input to separate delay lines at one-half the given rate.  The even samples are summed in pairs symmetrically about the center of the even delay line, and each pair is weighted according to a modified sin(x)/x function with simple coefficients which may be accomplished by additions and shifts, to eliminate the need for multipliers.  For data rate reduction the even sample pairs from the even delay line and the odd samples from the odd sample delay line are combined to form an average of the even samples and the odd samples which is the coded digital signal at one-half the given rate.  For data rate expansion a multiplexer may be used to combine the even and odd samples to produce an output digital signal at twice the given rate to decode the coded digital signal.

Abstract: ABSTRACT    An apparatus for generating phase modulated angular positional signals in digital form.  A phase tracking loop receives a phase modulated signal from the rotor of a resolver whose stator windings are excited in quadrature.  The phase output of the resolver is proportional to the angular displacement of the rotor.          Signals for exciting the stator windings of the resolver are applied in phase quadrature to a phase detector to develop an analog error signal when combined with the rotor output signal.  The analog phase error signal provides an output indicative of the angular displacement of the rotor.  The error signal is applied to a voltage controlled oscillator, converted to digital form, and combined with the excitation signals in a closed loop to force the error signal to a null, whereupon the indicated digital output angle is in coincidence with the angular displacement of the rotor shaft.

Abstract: In this drive control the regulating circuits for the rotational speed of a drive motor and of an eddy current brake are matched in their static and in their dynamic behavior so that a common regulator may be used for both regulating circuits. The matching is achieved by interposing a current regulation circuit for regulating the excitation current of the eddy current brake to the rotational speed regulating circuit. The output of the common regulator is supplied via a linearization member as a reference value to a regulator in the current regulation circuit during the deceleration phase. During the acceleration phase the output of the common regulator is supplied to a matching element matching the variation of the torque to the variation of the torque during the deceleration phase with respect to time. The output of the matching element is connected to the control member of the drive motor via a linearization member. By means of the linearization members the characteristics of a d.c.-shunt motor are approximately achievable. A distance regulating circuit is superposed on the rotational speed regulating circuit. The distance reference value is derived from jerk and acceleration magnitudes during the acceleration phase as well as during the deceleration phase, so that an optimum travel curve is achievable.
